JOHN SGHUMMER, OF CENTRALIA, WASHINGTON.

WINDOW-SCREEN.

To all whom it may concern Be it known that I, J OI-IN SOHUMMER, a citizen of the United States, residing at Centralia, in the county of Lewis and State of lVashington, have invented certain new and useful Improvements in Window- Screens, of which the following is a specification.

This invention relates to improvements in window screens, and has for one of its objects to provide a simply constructed device whereby a window screen is adapted to be connected to the sashes and movable therewith, and arranged to be retired into pockets above and below the window openings when not in use, and has for one of its objects to simplify and improve the construction and increase the efliciency and utility of devices of this character.

Another object of the invention is to provide a simply constructed screen device hav ing means whereby it may be readily coupled to and uncoupled from the window sash when not in use, or when it is desired to dispense with the screen.

With these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention, Figure 1 is a front elevation, viewed from the inside, of a portion of the side wall of a room including a window and its frame and easing; Fig. 2 is an elevation in section on the line 2-2 of Fig. 1; Fig. 3 is a transverse section on the line 33 of Fig. 1, the structure shown in Figs. 1, 2 and 3 being for a wood or frame building; Fig. 4 is a sectional detail illustrating the device arranged in a stone or brick building.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

The improved device may be applied to window sashes of different sizes, and comprises screen frames adapted to be coupled to the upper member of the upper sash and the lower member of the lower sash and movable therewith and retired into pockets within the frame work of the building above and below the window opening. No change is required in the construction of the window frame, except to form a recess in the upper or lintel member of the window frame for the passage of the screen frame which is Specification of Letters Patent.

Application filed March 11, 1913.

Patented Feb. 17, 1914. Serial No. 753,535.

coupled to the upper sash and a like recess in the sill member of the window to receive the screen frame for the lower sash.

In the drawings, the improved device is shown in Figs. 1, 2 and 3 applied to the window frame of a wood building, and in Fig. 4

the device is shown applied to a conventional brick or stone building, to illustrate changes necessary to be made to adapt the device to different structures. 1

The head member or lintel of the frame is represented at 10, the jamb or side members at 11, the main sill at 12, the sub-sill at 13,

upper sill 12 and the sub-sill 13 in the path u of the lower sash 19. The recess 20 is of less width than the thickness of the upper member of the sash 18 and is located next to the parting stop 17, while the recess 21 is of less width than the thickness of the lower sash 19 and is located next to the outer edge of the stool 1 1. The main sill member 12 is provided with a rain guard lip 22 next to the outer side of the recess 21, while the lower anember of the sash 19 is provided with a rabbet 23 to engage over the lip 22 and thus form a guard to prevent rain or snow from being driven into the recess 21 when the sash is closed. The upper member of the upper sash 18 is provided with a rabbet 2st to receive the lower edge of a screen frame 25, while the lower member of the lower sash 19 is provided with a similar rabbet 26 in its lower edge to receive the upper member of a similar screen frame 27. By this means the screen frames are supported in their engagement with the sash members and the passage of air and moisture prevented, as hereinafter explained.

The frame 25 is covered with the usual screen material represented at 28, while the frame 27 is likewise covered with screen material represented at 29. The screen frame 25 operates through the recess 20 while the screen frame 27 operates through the recess 21, and the screen frame 25 is of sufficient height so that the upper member of the frame remains constantly within the recess 20, while the frame 27 is of suflicient height 18 is a rock lever 32 having a lateral offset so that the lower member remains constantly l within the recess 21. The screen frame 25 is locked to the sash 18 by detachable fastening devices, while the frame 27 is similarly coupled to the, lower sash 19, so that when the sashes are moved vertically, the screen frames move with them. By this means, when the sashes 18--19 are closed, the screen frame 25 will be disposed entirely within the pocket formed therefor above the window frame, while the screen frame 27 will be disposed entirely within the pocket formed therefor below the sill.

Embedded in the lower member of the frame 25 are perforated plates 30, and piv-- oted at 31 to the upper member of the sash terminal to engage through the aperture in the plate 30. The rock levers 32 are each provided with an operating spring 34: to maintain them in locked relation to the plate. Embedded in the upper member of the frame 27 is a similar perforated plate 35, and pivoted at 36 to the lower member of the sash 19 is a lock lever 37 having a lateral offset 38 to engage through the aperture of the plate 35 and yieldably supported by a spring Any number of the embedded plates and the lock levers may be employed for each screen but generally two will be sufficient as shown. By this arrangement a simply constructed fastening device is provided whereby the screen frames may be coupled respectively to the sashes so that they move vertically with the sashes. At the same time the screen frames may be disconnected from the sas ies when not in use. hen the lower screen frame is disconnected from the lower sash 19, it will remain by gravity in its pocket and will not require other supporting means, but when the uppe' screen frame 25 is disconnected from the sash 18 and deposited in its pocket, a spring controlled bolt, represented at 40, is arranged to operate through the casing at any convenient point to engage such screen frame and hold the same suspended. By this simple arrangement, it will be obvious, that when the screens are required for use, they can be readily attached to their respective sashes by the action of the lock levers 3258 and move with the sash and thus cover and protect the open portions of the window, and then when the screens are not required, as for instance in cold weather, or when it is desired to have the windows unobstructed, the screens may be readily dcposited in the pockets, as before described.

Then the improved device is employed upon wood buildings the pockets for the screens will simply be formed within the spaces between the studding, as shown in Flgs. 1, 2 and 3, but when the improved dcvice is employed in connection with a brick or stone building, the pockets will preferably be formed of metal casings, preferably steel, which are located in suitable cavities formed in the walls of the building above and below the window openings, the metal lining members being represented conventionally at 41.

The improved device is simple in com struction, can be inexpensively applied and dispenses with detachable screens which are attached to the frame or stops independently of the sashes.

Having thus described the invention what is claimed as new is:

1. It window including a frame with a pocket in the lintel member comn'uinicating with the runway of the upper sash and pocket in the sill member communicating with the run-way of the lower sash, the upper sash having a rabbet in its upper member forming a stop shoulder and the lower sash having a rabbet in its lower member forming a stop shoulder, an upper screen frame engaging in the rabbet and against the stop shoulder of the upper sash and operating in the upper pocket, a lower screen frame engaging in the rabbet and against the stop shoulder of the lower sash and operating in the lower pocket, means attached to the upper sash and operating to comprc s the upper screen frame against the stop shoulder of the upper sash, and means attached to the lower sash and operating to compress the lower screen frame against the stop shoulder of the lower sash.

2. The combination with a window sash having a rabbet in one of its horizontal members forming a stop shoulder. of a screen frame engaging in said rabbet and hearing against said stop shoulder, and a device carried by said sash and operating to compress said screen frame against said shoulder and holding thescreen frame in detachable engagement with the sash.

3. A window having a pocket through its sill and with a stop rib externally of the pocket, a sash having an outer and an inner rabbet in its lower member, the outer rabbet engaging over the stop rib when the sash is closed and the inner rabbet forming a. stop slmulder, a screen frame engaging by its up per edge in the inner rabbet and extending in alinementwith the sash, and means for coupling said screen frame to said sash and holding the screen frame compressed againstthe stop shoulder.

In testimony whereof I affix my signature in presence of two witnesses.
